Currently Being ModeratedJul 9, 2010 9:29 AM (in response to Aston71!)I can barely hear the audio on video recording. Voice memo and speaker phone conversations work fine. It must be a software issue because the microphone does work.2x2.8 GHz Quad-Core Mac Pro, Mac OS X (10.6.3)
Currently Being ModeratedJul 9, 2010 7:25 PM (in response to Aston71!)I stopped by the apple store and they told me to try restoring my iPhone to see if that fixed the audio problem. It did not fix it.2x2.8 GHz Quad-Core Mac Pro, Mac OS X (10.6.3)
Currently Being ModeratedJul 10, 2010 10:51 AM (in response to Cribbage fan)I hear sound if I use my front camera while recording. Just if I'm using the back camera I hear no sound. I think it's a software bug. Maybe the near iOS4 update will fix it.Iphone4, iOS 4
Currently Being ModeratedJul 22, 2010 5:20 PM (in response to Aston71!)I have the same problem (and I've made sure the microphones were clear, tried powering on and off, tried restoring, etc. etc.). Does anyone know if there's a bug filed for this?iPhone 4, iOS 4, iOS 4.0.1

I'm having the same issue. Here is what I've tried that did not resolve the problem:
1. Restarted the phone.
2. Reset the settings.
3. Restore to factory settings.
After #3 I tested before putting my apps and data back on the device and then after I did that... nothing fixed the problem.
Going into the Apple Store tomorrow morning with an appointment to see what they can do.

Currently Being ModeratedMar 1, 2011 7:47 PM (in response to Aston71!)I was having this problem today. I would record video, but would not hear the sound. I made sure my volume was turned up. I could not record audio either with the native voice app. I was able to record my voice using the MosesNotes app.
With nothing to lose, I did a restore on my iPhone. Restored last night's backup and now I can record video with audio.imac9,1, Mac OS X (10.6.1)

I've never had any problems with my video recording until recently i discovered that the audio captured during video recording is extremely soft, close to nothing. The mic works in every other app, like voice recording, normal voice calls and even speakerphone. I wonder why there is only a problem with video recording. Anyone can help?
Running ios 4.3.1 all this while w/o any glitch until now.

I had this same problem -- *very* faint audio when recording video. This sounds silly, but here's what worked for me. There are two microphones on the phone. One at the bottom and one pinhole microphone at the top by the earphone jack. My phone had a tiny, tiny spec of dust in the top microphone hole. By *very* gently brushing it out with a needle, the microphone was clear again and videos again have crystal clear audio. The difference is akin to plugging your own ear. There's faint sound, but a world of difference when you clear it out.

A restore did not work for me, but a needle in the top microphone did. Thanks for this tip!
